1. A medical apparatus, comprising:
a casing that forms an exterior;
a single manipulation ring rotatably provided on an outer surface of the casing;
an optical sensor to receive a user manipulation, wherein the optical sensor is inside the casing to detect whether or not an opening formed in the casing is covered; and
control circuitry configured to
detect rotation of the single manipulation ring;
calculate a rotation direction and a rotation angle of the single manipulation ring based on a detection result;
execute a first function or a second function depending on the rotation direction and the rotation angle of the single manipulation ring calculated, wherein the first function is a different type of adjustment than the second function; and
switch a function executed by the control circuitry to the first function or the second function depending on a user manipulation of the optical sensor.
